  • Another disadvantage is caused by the fact that the known crimping apparatuses do not allow to correctly perform such a work on angles existing on collectors and water-boxes whereby often resulting in a poor tightness.
  • sections of the collector and the water-box to be connected together are surrounded by a belt of electric conductive metal, and then said belt is submitted for a very short period about a few milliseconds to the action of at least one pulse generated by a high electromagnetic field, operating substantially perpendicularly to the different sections of said belt, whereby obtaining the crimping of this belt on said collector and water-box.
  • FIG. 1 is a diagrammatic half-sectional view of an embodiment of a crimping device of the invention
  • FIG. 2 is an electric diagram to feed the device of FIG. 1;
  • FIGS. 3 are enlarged sectional views illustrating three embodiments of the invention in the preferred application for connecting water-boxes and collectors of a radiator for vehicle;
  • FIG. 6 is a partial sectional view illustrating the application of the invention on a two fluid tubular exchanger
  • FIGS. 7 and 8 are partial sectional views illustrating additional characteristics

  • FIG. 1 shows, in accordance with one embodiment of the invention, how the process of the invention is put into practice to ensure the fixing of water-boxes on the collectors of a radiator core.
  • the core comprises tubes -1 connected to heat dissipators 2, for
  • the material of the tubes 1, dissipators 2, collector's 3, 4 and water-boxes 5, 6 is not taken into consideration.
  • the tubes 1 can be made of brass, aluminum or stainless steel;
  • the dissipators 2 can be made of steel, copper or aluminum,
  • the collectors 3 and 4 can also be made of brass, steel, treated or not treated, even made of synthetic material; and it is the same for water-boxes 5, 6.
  • any usual assem bling method put into practice in technics can be applied, such as soft soldering, adhesively brazing, adhesively sticking, etc.
  • the core so to speak i.e., the tubes 1, the dissipators 2 and the collectors 3, 4 are assembled; and to connect the collectors to the water-boxes, the method is as follows.
  • a field shaping collar 7 is prepared preferably made of copper with beryllium and the inner wall 7a of said collar is shaped to have a form corresponding in section to the parts of collectors and water-boxes to be joined together. If the collectors and water boxes are rectangular with slightly rounded angles, then the inner wall 7a is made in a corresponding way. If the collector and- /or the water-box shows some recesses'or projections, then in the same way the wall 7a is shaped to at least approximately follow said recesses or projections.
  • the field shaping collar 7 is surrounded by at least one winding 8 and as shown on FIG. 2 the ends of the winding or of each winding are connected to a pulse generator for example to the two plates of a capacitor battery 9 respectively.
  • a switching component 10 is provided, for example a fast circuit-breaker which can be composed of an electronic device, said circuitbreaker being mounted in series between the capacitor battery 9 and winding 8.
  • a power transformer 11 is provided, the primary winding thereof being fed by mains l2.
  • the unit comprising the fields shaping collar 7 and winding 8 is mounted on a support 13 which delimits a supporting bed 14 on the top of which is put a waterbox, in the present case the box 6, with reference to FIG. 1.
  • This bed is designed to keep the water-box in a correct position in relation with the shaping collar 7.
  • the shaping collar is provided on wall 7a thereof, with a thin rim 15, for example made of synthetic material such as polytetrafluoroethylene or polyamide, said rim delimiting at the lower section thereof, a flange 15a used as a stop for a belt 16 centered by said rim 15,
  • the belt 16 is made of electric conductive material, for example aluminum,
  • This belt has also a similar shape as the collector and water-box to he slipped onto the latter.
  • the belt 16 is installed into rim 15, the waterbox 6 is installed and is centered by said belt 16 and kept at a suitable level by bed 14, then the radiator core is installed in such a way that the collector 4 thereof rests on the water-box 6 while being centered by belt 16.
  • the water-box 6a can be made of a relatively flexible material, for example of elastomere, and provided with a marginal flange 18 on which the belt 16 is set at the same time as on a moulding 19 of collector 4 which can in that casebe metallic.
  • the collector is made of electric conductive metal, that is for example made of brass, aluminum or steel, then it is the collector 4a (FIG. 3a) which can form a belt 16a on the peripheric edge thereof, said belt 16a being then set onto the marginal flange 18 of water-box 6a.
  • FIG. 4 shows that it is possible to place, between collector 4 and water-box 6b, a gasket 20 which can be made of soft material or of glue.
  • the water-boxes can be made of metal without any prejudice. This is shown on FIG. 5 on which the water-box is designated by 60 while the belt 16a is directly shaped by collector 40 as shown on FIG. 3a.
  • FIG. 6 illustrates an example in which the exchanger is composed ofa core of tubes 10 contained in an envelope 21, said tubes running into collector-plates 22 which are covered by end flanges 23 forming feeding boxes.
  • a belt 16b, made of conductive metal is then simultaneously used as a connection between the envelope 21, the collector-plate 22 and theend flange 23. From this figure it is noticed that the field causing the warping of belt 16b has for its effect to delimit in the latter, a groove 24 when care is taken to provide the collector-plate 22 whith a diameter smaller than the one of the envelope 21 and flange 23; this is used as a mark if it becomes necessary to saw said belt 16b to disassemble the unit.
  • the water-box as the one designated by reference 6d in FIG. 7, is made of material which can be warped even temporarily during the setting operation or when the material of the water-box shows some brittleness
  • the lower surface 25 of the marginal flange 18 thereof delimits a housing 26 in which the collector 4b is at least partially embedded with also eventually seal 27.
  • the collector 4b cooperates with the watenbox to form a very strong hollow girder, whereby preventing any temporary warping of said water-box.
  • FIG. 8 shows a development of FIG. 7 according to which the collector 4b is also embedded in an housing of the water-box 18 and besides, said figure shows that it is sometimes advantageous to also provide a peripheric groove or spaced-out recesses 28 in the lateral edge of marginal flange 18 of the water-box 6e.
  • a seal 29 can be placed between the collector and the water-box and, for example, said seal can be shaped as represented in FIG. 8.
  • FIGS. 9 to 11 illustrate a development of the invention providing a very good rigidity of the belt (then designated by Me) when put into place and further causing said belt to exert a permanent resilient pressure on the water-box 6f and on collector 4c.
  • the water-box 6f is provided at least at the four angles thereof with projecting ribs 30 the section of which is increasing from top to bottom of said water-box, these ribs presenting for example a rounded outline as shown on FIG. 10.
  • the two lateral sides 16 and 16 of the belt 16e are folded above the top of marginal flange 18 of the water-box and under the collector 4c which is, preferably, embedded as in FIG. 7 and 8.
  • the side 16 comes to a stop against said ribs; this increases the elongation to which the side 16, is subjected during the warping thereof.
  • said side 16 is only submitted to an elongation but no one of the sections thereof is submitted to a contraction.
  • the result is that the metal delimiting theside 16, stays under 5 train when folded, that makes the water-box be always applied on the top of the collector.
  • Relating to side 16 it has been noticed that the same result could be obtained if the ribs 30 were extended beneath the collector and that anyway a similar result could still be obtained even without extending said ribs.
  • said side 16 get folded as shown in FIGS. 10 and 11 forming at the angles of the belt a warped fold 31 which constitutes a kind of rib causing the metal of side 16;. to be also kept strained and also rendered more rigid because of the presence of said folds 31.
  • each collector 3 to each water-box 5 a belt 16f is utilized and the water-box 5 is supported by a bed 14 while the belt 16f centered by the water-box and the collector eventually rests on a projected flange 14a of bed 14.
  • the field shaping collar 7 is made up in the form of a single winding for example made of copper with beryllium having a shape corresponding to the one of belt 16f.
  • said shaping device tends to become rounded in the linear sections thereof, or presents a largeradius of curve, whereby resulting in bringing together the sections thereof having a small radius of curve to the angles of belt 16f and consequently in increasing the setting pressure in those areas where it has been deemed necessary to dispose of a more inportant force.
  • the warping of collar 7 can also be controlled and as shown in FIG. 13, support edges 36 or resilient blocks can be designed in some areas of the periphery thereof, which allows to accurately check the forces applied on the belt 16f whereby causing the setting thereof.
  • support edges 36 or resilient blocks can be designed in some areas of the periphery thereof, which allows to accurately check the forces applied on the belt 16f whereby causing the setting thereof.
  • FIGS. 13 and 14 it is possible as also shown in FIGS. 13 and 14 to fold at substantially 180 the edge 16f of said belt in order to pinch the turned-down edges of mutual centering 5 3 formed by the water-box 5 and the collector 3 respectively while the other edge l6f is folded at right angle on a peripheral support section of the water-box 5, ensuring a great strength to the finished assembling.
  • the magneto forming pulse is of sufficient strength to cause the material to fold over an angle of substantially 180 by its own inertia.
  • FIG. 14 illustrates an embodiment in which the shapin g collar comprises several superposed single windings 7 7 7,, which are respectively connected to separate generators or to separate generators or to separate outputs of a same I generator whereby the electrical pulse applied to each single winding can be adjusted.
  • a more important force can be applied from single winding 7 to cause the folding of edge 16f, only from belt 7 to avoid any warping of the turned-down edges of the collector and water-box, while a strength of intermediary importance can be generated from single winding 7 to ensure the folding of edge 16f
  • the invention is not restricted to the embodiments shown and described in detail for various modifications thereof can moreover be applied to it without departing the scope of the invention.
  • the rim can be removed when the belt is directly formed by the collector.
  • the capacitor working in relaxation can be replaced by various pulse generators as by electronic generators rendering eventually possible to successively apply several pulses to complete shaping of belt 16.
  • a method for joining together two sections each having external flanges of substantially rectangular shape comprising the steps of:
  • a method according to claim 1 comprising the further step on providing ribs on at least the external flange of one of said two sections.
  • annular distortable ring is provided by fitting an extension on one of the two sections.
  • annular distortable ring is provided by fitting an independent metal belt around said flanges between the same and said metal collar.
  • a method according'to claim 1 comprising the further step of adjusting the shape of said metal coliar at suitable portions thereof.- I 4
